工程造价估算模型研究与基于层次分析法的BP神经网络模型应用

摘要

This paper describes the concept and classification of project estimation model, the basic concepts, basic structure and algorithm principle of neural networks, establishes a BP neural network project cost prediction model based on AHP, conducts case studies according to the model by using MATLAB neural network toolbox, and elaborates its specific application process. Studies show that it is entirely feasible to forecast project cost by using the BP neural network.%本文阐述了工程估算模型概念、分类，神经网络的基本概念、基本结构和算法原理，建立了基于层次分析法的BP神经网络的工程造价预测模型，并根据模型借助MATLAB神经网络工具箱对案例分析，对其具体应用过程作了阐述。研究表明使用BP神经网络来进行工程造价预测是完全可行的。
